     *

    /**
     * The `Hmac` class is a utility for creating cryptographic HMAC digests. It can
     * be used in one of two ways:
     *
     * * As a `stream` that is both readable and writable, where data is written
     * to produce a computed HMAC digest on the readable side, or
     * * Using the `hmac.update()` and `hmac.digest()` methods to produce the
     * computed HMAC digest.
     *
     * The {@link createHmac} method is used to create `Hmac` instances. `Hmac`objects are not to be created directly using the `new` keyword.
     *
     * Example: Using `Hmac` objects as streams:
     *
     * ```js
     * const {
     *   createHmac
     * } = await import('crypto');
     *
     * const hmac = createHmac('sha256', 'a secret');
     *
     * hmac.on('readable', () => {
     *   // Only one element is going to be produced by the
     *   // hash stream.
     *   const data = hmac.read();
     *   if (data) {
     *     console.log(data.toString('hex'));
     *     // Prints:
     *     //   7fd04df92f636fd450bc841c9418e5825c17f33ad9c87c518115a45971f7f77e
     *   }
     * });
     *
     * hmac.write('some data to hash');
     * hmac.end();
     * ```
     *
     * Example: Using `Hmac` and piped streams:
     *
     * ```js
     * import { createReadStream } from 'fs';
     * import { stdout } from 'process';
     * const {
     *   createHmac
     * } = await import('crypto');
     *
     * const hmac = createHmac('sha256', 'a secret');
     *
     * const input = createReadStream('test.js');
     * input.pipe(hmac).pipe(stdout);
     * ```
     *
     * Example: Using the `hmac.update()` and `hmac.digest()` methods:
     *
     * ```js
     * const {
     *   createHmac
     * } = await import('crypto');
     *
     * const hmac = createHmac('sha256', 'a secret');
     *
     * hmac.update('some data to hash');
     * console.log(hmac.digest('hex'));
     * // Prints:
     * //   7fd04df92f636fd450bc841c9418e5825c17f33ad9c87c518115a45971f7f77e

     * * Using the `sign.update()` and `sign.sign()` methods to produce the

     *
     * The {@link createSign} method is used to create `Sign` instances. The

     * Example: Using `Sign` and `Verify` objects as streams:
     *
     * ```js
     * const {

     * Generates a new asymmetric key pair of the given `type`. RSA, RSA-PSS, DSA, EC,
     * Ed25519, Ed448, X25519, X448, and DH are currently supported.
     *
     * If a `publicKeyEncoding` or `privateKeyEncoding` was specified, this function
     * behaves as if `keyObject.export()` had been called on its result. Otherwise,
     * the respective part of the key is returned as a `KeyObject`.
     *
     * It is recommended to encode public keys as `'spki'` and private keys as`'pkcs8'` with encryption for long-term storage:
     *
     * ```js
     * const {
     *   generateKeyPair
     * } = await import('crypto');
     *
     * generateKeyPair('rsa', {
     *   modulusLength: 4096,
     *   publicKeyEncoding: {
     *     type: 'spki',
     *     format: 'pem'
     *   },
     *   privateKeyEncoding: {
     *     type: 'pkcs8',
     *     format: 'pem',
     *     cipher: 'aes-256-cbc',
     *     passphrase: 'top secret'
     *   }
     * }, (err, publicKey, privateKey) => {
     *   // Handle errors and use the generated key pair.
     * });
     * ```
     *
     * On completion, `callback` will be called with `err` set to `undefined` and `publicKey` / `privateKey` representing the generated key pair.
     *
     * If this method is invoked as its `util.promisify()` ed version, it returns
     * a `Promise` for an `Object` with `publicKey` and `privateKey` properties.
     * @since v10.12.0
     * @param type Must be `'rsa'`, `'rsa-pss'`, `'dsa'`, `'ec'`, `'ed25519'`, `'ed448'`, `'x25519'`, `'x448'`, or `'dh'`.
